User Plane Function Distribution and Local Break-Out

UPF Distribution/Shunting capability -- distributing User Plane Functions in appropriate Data Center Facilities on qualified compute hardware for routing the traffic to desired applications and network/processing functions/applications.
Local Break-Out (LBO) – Examples: video traffic offload, low latency services, roaming optimization.

UPF Location Selection

Location Services -- location of a specific UE, or identification of UEs within a geographical area, facilitation of server-side application workload distribution based on UE and infrastructure resource location.

Assumptions:

MNO provides a Location Service (LS) compliant with OMA Zonal Presence API (OMA-TS-REST_NetAPI_ZonalPresence)
A Public Cloud Edge (PCE) instance is associated with a Zone (collection of Access Points such as small cells) provided by an MNO
A 3rd-Party Edge (3PE) instance is associated with a Zone (collection of Access Points such as small cells) provided by an MNO
An application/workload in the PCE requires Location Information (e.g. coordinates of the Access Point) for the UE/subscriber
An application/workload in the 3PE requires Location Information (e.g. coordinates of the Access Point) for the UE/subscriber
PCEI Enabler facilitates Zonal Presence API Request/Response routing between PCE and the MNO LS and between the 3PE and the MNO LS
